diamong [38]

Answer:

0.070

Step-by-step explanation:

Y = number on trial

Y has a negative binomial distribution

r = 3

P = 30% = 0.3 probability of positive indication.

P(Y = 11) probability of 11 employees that must be tested to get 3 positives

Y-1Cr-1*p^r*q^(y-r)

Y-1 = 11-1 = 10

r-1 = 3 -1 = 2

10C2 x 0.3³x0.7⁸

45x0.027x0.05764801

= 0.070

This is the probability that 11 employees must be tested to get 3 positives.

sergejj [24]

Answer:

VW = 44

Step-by-step explanation:

the line VX is parallel to ZY and intersects the other 2 sides of the triangle then it divides those sides proportionally , that is

$\frac{ZV}{VW}$ = $\frac{YX}{XW}$ ( substitute values )

$\frac{22}{VW}$ = $\frac{18}{36}$ = $\frac{1}{2}$ ( cross- multiply )

VW = 2 × 22 = 44

Simplify the following : x^2y^-3 / x^5y^2

Likurg_2 [28]

Answer:

Step-by-step explanation:

$\frac{a^{m}}{a^{n}}=a^{m-n}\\\\a^{-m}=\frac{1}{a^{m}}\\\\\\\frac{x^{2}y^{-3}}{x^{5}y^{2}}=x^{(2-5)}*y^{(-3-2)}\\\\ = x^{-3}*y^{-5}\\\\=\frac{1}{x^{3}y^{5}}$
